3-D成像新技术--光学外差扫描全息术

摘要

The theories behind both optical heterodyne scanning holography, a novel 3-D imaging technique, and circular grating optical scanning holography, a holographic technique based on optical heterodyne scanning holography, and its advantages over traditional optical heterodyne scanning holography, are discussed in detail, and some of optical heterodyne scanning holograph's potential applications, including 3-D remote sensing and medical imaging, are presented with typical examples given.%介绍了一种新的3-D成像技术-光学外差扫描全息术的基本原理,以及基于光学外差扫描全息术基本原理的环形光栅光学扫描全息术,描述了其与传统的光学外差扫描全息术相比具有的优势.最后,以光学外差扫描全息术在三维空间滤波、遥感和三维混浊液体中成像应用为例,阐述了这一新技术的应用前景.
